UV analyzers are divided into many series, including three purpose UV analyzers, dark box UV analyzers, portable UV analyzers, etc. Different UV analyzers have different uses. Ultraviolet light of different wavelengths is used to observe and take photos of DNA and RNA electrophoresis gel samples, detect proteins and nucleotides. It is suitable for nucleic acid electrophoresis analysis, detection, PCR product detection, DNA fingerprint analysis, paper layer analysis or thin-layer analysis. It is an ideal instrument for conducting RFLP research and RAPD product analysis. This machine can observe and photograph the electrophoresis gel without operating in the dark room, and can also be equipped with a protein detector to observe and photograph the protein. UV is strong and uniform. Can be connected to reflector lights, etc. The ZF-7A portable UV analyzer is one of our UV instrument series products. The machine adopts a one-time molded plastic shell and an electronic integrated block to start the light source, equipped with high-intensity ultraviolet lamps, which have the advantages of small size, light weight, and easy use.
